StringValidator validates that XML content is a W3C string type.
The string datatype represents character strings in XML. The
value space of string is the set of finite-length sequences
of characters (as defined in [XML 1.0 Recommendation
(Second Edition)]) that match the Char production
from [XML 1.0 Recommendation (Second Edition)].
A character is an atomic unit of communication; it
is not further specified except to note that every
character has a corresponding Universal Code Set
code point ([ISO 10646],[Unicode] and [Unicode3]),
which is an integer. |
